Guards
When Wallace and Gromit get to the the maze (where the guards are located) in Act 4 Part 1, go to the box at the end of the hall in the maze. It will have a paw print. Go into the box. You will notice a guard walking back and forth in his area. There are two guards, and three buttons. When the guards are not looking, press the button. If the guards see you, they will shoot you, even if you are in the box. For this reason, if you block his pathway he will shoot the box that you are in and you will have to start again, and the buttons will be stationary. Also, if they cannot see you, you can run, and not sneak. Note: Once you are pressing the button, at the end of the maze there will be a light blue cube. You will raise the cube if you press the button. Press all three buttons in order to escape from the guards.
